RELATED APPLICATION

This is application is a continuation-in-part of application Ser. No.11/477,514 filed on Jun. 30, 2006, for “Method And System For ProvidingSignatures For Machines,” which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates generally to a method and system forinspecting machines, and more particularly, to a method and system foridentifying machines.

BACKGROUND

Machines and machine components have routinely been the target ofthieves, especially when there is a need for equipment, such as after anatural disaster. Stolen machines may be stripped and sold for parts,and therefore, create difficulties for authorities and machine owners toidentify missing parts. To assist with identifying machines and machinecomponents, markings are used, such as labels, etchings, etc., thatuniquely identify a given component or machine. However, these markingsmay be removed or altered to change the identification information.

Furthermore, law enforcement officials may not be trained to identifymachines properly. For example, transported machines that are subject toinspection may have identification information printed on a component orsticker attached to the machine. However, alterations to theidentification information frustrate the machine identification process.That is, law enforcement attempts to accurately identify machines withaltered markings and identifications hinder the ability to locatemissing machines and components.

One method of locating a missing vehicle is described in U.S. Pat. No.5,418,537 (the '537 patent) to Bird. In the system disclosed by the '537patent, a vehicle owner notifies a vehicle location service center thata vehicle is missing. In response, the vehicle location service centerbroadcasts a paging request. The paging request is received by thevehicle, which sends its present location to the vehicle locationservice center so that the vehicle can be recovered.

Although the system of the '537 patent provides a method for recoveringmissing vehicles by broadcasting a paging request to the missingvehicle, the method has some drawbacks. For example, once the missingvehicle is located electronically, there is a time delay until theactual retrieval of the vehicle because the person retrieving themissing vehicle must travel to the location of the vehicle. Thus, themissing vehicle may be moved while the person sent to retrieve themissing vehicle is en route to the vehicle's detected location.Furthermore, if the paging responder or a similar device is removed fromthe vehicle, the vehicle is unable to respond to the paging request andthus unable to be located.

The disclosed system is directed to overcoming one or more of theproblems set forth above.

DETAILED DESCRIPTION

FIG. 1 illustrates an exemplary machine 10 having one or more components11. A machine component 11 may be an electronic, electrical, mechanical,electro-mechanical, etc., portion of machine 10 that performs someoperation related to the overall operation of machine 10 (e.g., ahydraulic component, an engine, a transmission, etc.). Machine 10 mayembody a fixed or mobile machine that performs some type of operationassociated with an industry such as mining, construction, farming,transportation, or any other industry known in the art. For example,machine 10 may be a commercial machine, such as a truck, crane, earthmoving machine, mining vehicle, material handling equipment, farmingequipment, marine vessel, aircraft, an excavator, a dozer, a loader, abackhoe, a motor grader, a dump truck, or any type of machine thatoperates in a work environment such as a construction site, mine site,power plant, etc.

Machine 10 may be equipped with a data communication system 12, whichincludes at least one electronic control module (ECM) 13, a gatewayprocessor device 14, a transceiver device 15, and a global positioningsatellite (GPS) device 16. Although the following description relates tothe identification of machine 10, one or more machine components 11 mayeach also be equipped with data communication system 12. Accordingly, incertain embodiments, machine 10 may include multiple data communicationsystems 12 mounted on one or more separate machine components 11.

Data communication system 12 may be a system configured to collect andtransmit machine data, location data, and identification data. In oneembodiment, ECM 13 stores machine data including, for example,identification information specific to machine 10. For example, theidentification information may include a machine identifier (e.g., aserial number, registration number, or other information assigned tomachine 10). Further, ECM 13 may collect and/or store other types ofmachine data, such as scheduling data (e.g., when machine 10 isscheduled to change location and/or how long machine 10 is scheduled toremain at a location, identification of types of authorized operationsduring scheduled shifts, etc.), machine operational data (e.g.,operational historical parameter data (e.g., oil pressure, motor speed,temperatures, fluid levels, and/or other parameter data related to theoperation of machine 10 or a component 11)), timings, fault codes, etc.ECM 13 may collect the machine data from one or more machine components11. Alternatively, or in addition, ECM 13 may collect machine data fromone or more other ECMs 13 associated with one or more other machinecomponents 11.

ECM 13 may also be associated with at least one sensor (not shown) formonitoring and recording at least one type of machine data. For example,an engine ECM may receive signals from engine sensors, such as, forexample, an atmospheric pressure sensor, a fuel flow sensor, a boostpressure sensor, a water temperature sensor, and an engine speed sensor.Additional sensors may be included to measure other properties of theengine as necessary, as would be apparent to one skilled in the art.Another exemplary ECM is a transmission ECM, which may be associatedwith sensors that monitor the transmission, such as a gear code sensor,a transmission output speed sensor, and a differential oil temperaturesensor. Other sensors may be associated with the transmission ECM aswould be apparent to one skilled in the art.

As explained, machine 10 may include multiple ECMs 13. Each of theseECMs 13 may be different types of ECMs 13. For example, machine 10 mayinclude a hydraulic system ECM, a chassis ECM, and/or a brake/coolingECM. These other ECMs may also be associated with one or more sensorsfor collecting machine data related to one or more machine components11, such as a hydraulic system, the chassis, the brake/cooling systems,etc. Other sensors and ECMs may be included for collecting machine datarelated to other components as would be apparent to one skilled in theart. Each ECM may be associated with one or more sensors, and thespecific types of sensors and the number of sensors associated with eachECM may be based on the type of application and information to beobtained by the sensors.

Gateway processor device 14 includes one or more processor devices thatexecute program instructions to perform various functions such asrequesting and/or receiving information from ECM 13 and GPS device 16.Further, gateway processor device 14 may generate messages to transmitto an off-board system, such as a service center 20 (FIG. 2). Gatewayprocessor device 14 may be configured with different types of hardwareand/or software (e.g., a microprocessor, a gateway, a product linkdevice, a communication adapter, etc.). Gateway processor device 14 mayalso provide interface functions for transmitting data to, and receivingdata from, data communication system 12. Further, gateway processordevice 14 may execute software for performing one or more functionsconsistent with the disclosed embodiment. Also, gateway processor device14 may include storage device(s) for maintaining data for use by one ormore on-board modules (e.g., ECM 13), or one or more off-board systems(e.g., service center 20). For example, gateway processor device 14 maybe configured to perform protocol conversions (e.g., tunneling andtranslations), intelligent routing, and server-based operations, such asdata provisioning, application provisioning, Web server operations,electronic mail server operations, data traffic management, and anyother type of server-based operations that enable data communicationsystem 12 to retrieve, generate, and/or provide data with off-boardsystems, e.g., service center 20. For clarity of explanation, FIG. 1shows gateway processor device 14 as a distinct element. However,“gateway” functionality may be implemented via software, hardware,and/or firmware within other one or more on-board modules, such as ECM13, which communicates with off-board systems. Thus, gateway processordevice 14 may, in certain embodiments, represent functionality or logicembedded within another element.

Transceiver device 15 includes one or more devices that transmit andreceive information, such as information collected and stored by gatewayprocessor device 14 from ECM 13 and GPS device 16. Transceiver device 15may transmit the information to an off-board system, such as servicecenter 20. Further, transceiver device 15 may receive information, suchas requests for machine information from service center 20.Alternatively, transceiver device 15 may represent separate transmissionand receiver devices, or other devices for providing a communicationinterface between machine 10 and service center 20.

GPS device 16 generates location data, e.g., GPS coordinates, formachine 10 based on data from a satellite, local tracking system, or anyother position sensing system known in the art. The location data may becollected by gateway processor device 14 and may be transmitted toservice center 20 via transceiver device 15.

FIG. 2 illustrates an exemplary communication system 60 includingmachine 10, service center 20 including a machine information database22, a network 30 including, e.g., one or more additional wireless and/orwire-line communication networks (e.g., satellite networks, RF networks,fiber optic or coaxial cable based networks, twisted pair telephone linenetworks, or any other type of communication network), and otherentities 40, e.g., owners (not shown), dealers 42, law enforcement 44,and vendors 46. According to certain embodiments, communication system60 may perform one or more processes for identifying and/or locatingmachines 10 and/or machine components 11 implemented with a datacommunication system 12. The interaction within communication system 60to locate and identify a machine 10 is described below with reference toFIG. 3.

FIG. 3 is a flow chart showing an exemplary machine locating processconsistent with certain disclosed embodiments to collect and storeinformation regarding machine 10 and/or component 11 to locate a missingmachine 10 and/or component 11. In one embodiment, service center 20receives machine data from data communication system 12 associated withmachine 10 and/or component 11 (step 102). As described above, themachine data may include identification information assigned to machine10 and/or component 11, machine data reflecting operationalcharacteristics of machine 10 and/or machine component 11, etc. Forexample, the machine data may include one or more machine parameters,e.g., a machine identifier, a historical operational parameter, worksite information or other scheduling operational parameter, and/or afault code. The machine data is unique to a particular machine 10 and/orcomponent 11 and may include a series of values or a string of digits.Service center 20 may also receive location data related to machine 10and/or component 11, which is determined using GPS device 16, formachine 10 from data communication system 12.

Service center 20 may store the machine data received from machine 10and/or component 11 in machine information database 22 (step 104). Steps102 and 104 may be executed one or more times during the lifetime ofmachine 10 (e.g., following an assembly of machine 10, before machine 10has been delivered to a work site, and/or after delivery of machine 10to the work site). Further, steps 102 and 104 may be executed once,after a predetermined event has occurred, or periodically at regulartime intervals.

During operation, machine 10 and/or component 11 may periodically, or asdemanded by service center 20, provide a status report to service center20. For example, at the end of a shift for machine 10 (e.g., at the endof the day), machine 10 and/or component 11 may automatically provide astatus report, including location data, scheduling data, and/or machinedata, to service center 20.

Aspects related to certain embodiments enable the machine data to beused to locate and verify the identity of a machine or machinecomponent. In circumstances where a machine 10 and/or component 11 isreported to be in an abnormal condition, such as when it is missing(e.g., stolen, not returned at end of lease, moved from authorizedlocations, performing operations or tasks outside defined thresholds ortime constraints, unscheduled operation, etc.), trigger events may beimplemented to initiate processes for locating and/or verifying theidentity of the inspected machines or components. Thus, machine 10and/or component 11 may be determined to be missing based on anunscheduled trigger event, e.g., starting, changing operations, changingoperators, moving, etc. For example, gateway processor device 14 maystore scheduling data for machine 10 indicating when machine 10 isscheduled to operate and when it is scheduled not to operate. Gatewayprocessor device 14 may also receive machine data (e.g., engine datafrom an engine ECM indicating when the engine has started, transmissiondata from a transmission ECM indicating when the transmission isoperating, etc.). Gateway processor device 14 may compare the schedulingdata to the machine data, e.g., in real time or periodically, todetermine whether there is a conflict (i.e., machine 10 and/or component11 is operating when it is not scheduled). As a result, gatewayprocessor device 14 may generate and send a reporting message to servicecenter 20 via transceiver device 15 indicating that machine 10 and/orcomponent 11 is missing. The reporting message may include machine data,such as identification information used by service center 20 to identifymachine 10 and/or component 11 from other machines and/or componentslisted in machine information database 22. Alternatively, instead ofmissing machine 10 sending the reporting message directly to servicecenter 20, an owner of missing machine 10 and/or component 11, oranother entity 40 (e.g., dealers 42, law enforcement 44, and vendors 46)may generate and send the reporting message to service center 20 afterdetermining that the machine is missing.

In another embodiment, service center 20 may store scheduling data formachine 10 and/or component 11. Further, service center 20 may receivemessages periodically from machine 10 and/or component 11 that includelocation data for machine 10 and/or component 11. The messages receivedfrom machine 10 and/or component 11 may also include otheridentification information, such as the machine data used to identifymachine 10 and/or component 11. Service center 20 may compare thelocation data to the stored scheduling data to determine whether thereis a conflict. If so, service center 20 may identify an abnormalcondition for machine 10 and/or component 11.

Service center 20 receives the message reporting that machine 10 and/orcomponent 11 is missing (step 106). Alternatively, service center 20 maydetermine that machine 10 and/or component 11 is missing based on otherinformation (e.g., machine data). Service center 20 uses machine dataincluded in the reporting message to identify the machine dataassociated with machine 10 and/or component 11 in machine informationdatabase 22. Service center 20 may then flag the information in machineinformation database 22 associated with missing machine 10 and/orcomponent 11 (step 108). Service center 20 may also report the loss tolaw enforcement 44 or other entities 40 (step 110).

After flagging the machine data in machine information database 22,service center 20 may also send command messages through network 30 tocommand all missing machines 10 and/or components 11 that are flagged inmachine information database 22 to reply with a locating message (step112). In response to the command message from service center 20, missingmachine 10 and/or component 11 may transmit the locating message toservice center 20 via network 30 (step 114). The locating message mayinclude location data associated with missing machine 10 and/orcomponent 11 determined by GPS device 16 and machine data includingidentification information associated with missing machine 10 and/orcomponent 11 (e.g., one or more historical operational parameters,scheduling operational parameters, and/or other machine data used touniquely identify machine 10 and/or component 11).

In one embodiment, the specific parameters of machine data provided bymissing machine 10 and/or component 11 in the locating message may bespecified by service center 20 in the command message. For example, inthe command message, service center 20 may request that missing machine10 include in the locating message the same parameters used to identifythe machine 10 in machine information database 22. In anotherembodiment, the specific parameters of identification informationprovided by missing machine 10 and/or component 11 in the locatingmessage may be determined automatically by missing machine 10 and/orcomponent 11. Machine 10 and/or component 11 stores informationidentifying the specific parameters used to identify the machine 10 inmachine information database 22 and may send the specified parameters toservice center 20 when requested.

Service center 20 compares the received machine data to the machine dataassociated with machines 10 and/or components 11 stored in machineinformation database 22 (step 116). Because the same parameters are usedto identify machine 10 and/or component 11, the machine data for machine10 and/or component 11 received in the locating message may be identicalto stored machine data for the same machine 10 and/or component 11 thatis stored in machine information database 22. In one embodiment, themachine data may be substantially identical. That is, sets of data aresubstantially identical when they are equal to within a predeterminedrange, threshold, etc., of sets of data, such as a percentage value(e.g., 1%), a decimal value, (e.g., within 0.0001, 0.001, 0.01, 0.1,etc.), or any other type of threshold or range. Thus, when the machinedata received in the locating message matches (or substantially matches)one of the sets of machine data listed in database 22, service center 20may determine the identity of missing machine 10. The comparison of themachine data may require an exact match or a substantial match. Forexample, to attain an exact match, service center 20 may determine thatthe machine data from the locating message matches one of the sets ofmachine data stored in database 22 when each digit in the set of machinedata from the locating message is identical to a corresponding digit ofone of the sets of machine data stored in database 22 (e.g., 00111 and00111). On the other hand, to attain a substantial match, service center20 may identify machine 10 and/or machine component 11 when apredetermined number of digits (or a predetermined percentage of digits,etc.) match (e.g., 00111 and 0011x).

For example, the locating message from missing machine 10 and/orcomponent 11 may include location data and an identifier. When servicecenter 20 receives the locating message, service center 20 compares theidentifier received from missing machine 10 and/or component 11 in thelocating message to the identifiers stored in machine informationdatabase 22 for the missing machines. If there is a match, then theidentity of missing machine 10 and/or component 11 has been determined,and service center 20 sends a message to machine 10 and/or component 11to derate its performance, e.g., by derating engine speed of the engineassociated with machine 10 and/or component 11 (step 118). By deratingengine speed, machine 10 and/or component 11 may be capable ofoutputting only a fraction of its normal power. For example, machine 10and/or component 11 may be prevented from moving at higher speeds andmay be limited to moving at slower speeds or a crawl, and/or may nothave sufficient power to dig or perform other types of operations.

Alternatively, if machine 10 and/or component 11 is in the middle of ajob, service center 20 may transmit a message to machine 10 and/orcomponent 11 to derate the engine speed after completing the job. Forexample, to avoid safety problems, service center 20 may send a commandthat instructs ECM 13 to derate the engine speed after the machineand/or component is shut down manually. Thus, machine 10 and/orcomponent 11 can complete operations, but the engine speed will bederated when it is started up again after shutdown.

After determining the identity of missing machine 10 and/or component11, service center 20 may also send a missing machine notificationmessage to one or more designated entities 40 (e.g., owners, dealers 42,law enforcement 44, and/or vendors 46) (step 120). The missing machinenotification message identifies missing machine 10 and/or component 11and may include, for example, a message indicating that missing machine10 and/or component 11 is reported as missing, a machine identifier,and/or location data received in the locating message from missingmachine 10 and/or component 11. This information may be used toidentify, locate, retrieve, and/or return machine 10 and/or component 11to its owner.

Service center 20 may also store location data for entities 40 anddetermine one or more entities 40 that are within a selectedgeographical range from missing machine 10 and/or component 11 based onthe location data received in the locating message from missing machine(e.g., within a predetermined radius from missing machine 10 and/orcomponent 11). Service center 20 may send the missing machinenotification message to one or more geographically closest entities(step 122).

A portable device 50 (FIG. 2) may also be used to determine the identityof machine 10 and/or component 11. Portable device 50 may be a handheldor portable device used by one or more entities 40, e.g., dealers 42,law enforcement 44, and/or vendors 46. Portable device 50 may be ahandheld computer (e.g., a laptop, personal digital assistant (PDA),etc.), implemented using, for example, PALM® or PocketPC® technology andwireless capabilities. Entity 40 may use portable device 50 to receiveinformation using, for example, a sensor (e.g., an RFID reader or barcode reader) that gathers information from a communication port 18 onmachine 10 and/or component 11. The communication port 18 is connectedto gateway processor device 14 to allow the information stored ongateway processor device 14 and/or ECM 13 to be transferred to portabledevice 50. Alternatively, a wireline link may be provided to removablyattach portable device 50 to communication port 18, e.g., a UniversalSerial Bus (USB) port, RS 232 port, or a port using anothercommunication protocol in data communication system 12. Entity 40 may beable to access information received from gateway processor device 14 byexecuting software performed by portable device 50. Portable device 50may also include a transceiver device 52 that allows portable device 50to transmit information to and receive information from service center20. Transceiver device 20 may transmit or receive information viawireless or wireline network to service center 20.

In one embodiment, portable device 50 may read machine data (e.g.,identification information) from communication port 18 on machine 10and/or component 11 and may transmit the machine data to service center20 (step 130). The specific parameters of the machine data read byportable device 50 may be identified based on information stored inportable device 50.

Service center 20 may compare the received machine data to machine dataassociated with one or more machines and/or components stored in machineinformation database 22 (step 132). Service center 20 may identifymachine 10 and/or component 11 if, for example, the received machinedata matches the machine data for a machine 10 and/or component 11listed in machine information database 22. After determining theidentity of machine 10 and/or component 11, if it is determined thatmachine 10 and/or component 11 is flagged as a missing machine and/orcomponent, service center 20 may send a missing machine notificationmessage to portable device 50. The missing machine notification messagemay include machine data such as a machine identifier and/or locationdata.

For example, portable device 50 may read machine data (e.g.,identification information) from machine 10 and/or component 11 and maytransmit the machine data to service center 20. Service center 20compares the machine data received from portable device 50 to themachine data stored in machine information database 22 for flaggedmissing machines and/or components. If the machine data read by portabledevice 50 matches (or substantially matches) one of the sets of machinedata stored in machine information database 22, service center 20 maygenerate data reflecting that the identity of machine 10 and/orcomponent 11 is determined. After determining the identity of machine 10and/or component 11, service center 20 may determine whether machine 10and/or component 11 is flagged as a missing machine. If so, servicecenter 20 may send a missing machine notification message to portabledevice 50. The missing machine notification message may include amachine identifier, location data, and any other information related tothe machine (e.g., identity of the owner, contact information, etc.).

Alternatively, or additionally, portable device 50 may also execute aprocess that determines the identity of machine 10 and/or component 11(step 148). To do so, portable device 50 may execute processes similarto those described above in connection with service center 20. Forexample, portable device 50 may compare the machine data read frommachine 10 and/or component 11 against a set of stored machine datadownloaded from service center 20. Portable device 50 may store datathat is also stored in machine information database 22 and may receiveperiodic updates from service center 20. If the machine data read fromportable device 50 matches (or substantially matches) one of the storedsets of machine data, portable device 50 may generate data reflectingthat the identity of machine 10 and/or component 11 has been determined.Portable device 50 may send this message to service center 20 forfurther processing. Thus, portable device 50 may be used to identifymachine 10 without having to transmit the machine data that it readsfrom machine 10 and/or component 11 to service center 20. Afterdetermining the identity of machine 10 and/or component 11, portabledevice 50 may also determine if machine 10 and/or component 11 isflagged as a missing machine and may notify service center 20. Then,service center 20 may send a missing machine notification message todesignated entities 40, e.g., dealers 42, law enforcement 44, and/orvendors 46.

Further, after determining that machine 10 and/or component 11 is amissing machine, portable device 50 may, via direction by service center20 or by executing software stored on portable device 50, generate andsend a message to machine 10 and/or component 11 commanding it to derateits performance (step 134). Alternatively, if machine 10 and/orcomponent 11 is in the middle of a job, portable device 50 may transmita message to machine 10 and/or component 11 to derate its performanceafter completing the job, a task, or any other type of event, etc.

INDUSTRIAL APPLICABILITY

The disclosed embodiments enable machines to be accurately identifiedand located. For example, machine 10 and/or component 11 mayautomatically send messages to service center 20 reporting that it isoperating under an abnormal condition (e.g., stolen, not returned at endof lease, moved from authorized locations, performing operations ortasks outside defined thresholds or time constraints, unscheduledoperation, etc.). Service center 20 may then automatically send missingmachine notification messages to designated entities, e.g., local lawenforcement, vendors, and dealers. Thus, these entities may be updatedas to machine status, such as thefts. This reduces the time to recover astolen machine, which for example may reduce the negative impact on themachine owner's business.

In one embodiment, a database listing missing machines 10 and/orcomponents 11 may be maintained or it may be used to contact the missingmachines 10 and/or components 11. In situations where a missing machine10 and/or component 11 may be unable to respond immediately to a messagefrom service center 20 instructing machine 10 and/or component 11 torespond with its location data (e.g., because a battery in machine 10and/or component 11 is removed or is dead), machine 10 and/or component11 may delay its response (e.g., when the battery is replaced).Therefore, service center 20 may be able to contact missing machine 10and/or component 11 by sending out the command message periodically.

In another embodiment, portable devices 50 may be provided to inspectionagents (e.g., law enforcement, customs agents, dealers, etc.) for useduring inspection of machine 10 and/or component 11 (e.g., at a stop andcheck on the highway, at a border, in a dealer lot, etc.). An inspectionagent may be notified in response to machine 10 and/or component 11determining that it has been stolen and/or when the owner of machine 10and/or component 11 notifies service center 20. Furthermore, aninspection agent may use portable device 50 to properly identify amachine 10 and/or component 11 that is being inspected and be notifiedif the machine has been reported missing. Accordingly, if the machineidentification information inscribed on the machine is not readableand/or data communication system 12 on machine 10 and/or component 11 isunable to transmit identification information (e.g., transceiver device15 is removed or damaged), the inspection agent may use portable device50 to read the identification information from data communication system12 on machine 10 and/or component 11 to determine its status.

In addition, after identifying a missing machine, service center 20 orportable device 50 may transmit a message to the missing machine and/orcomponent to derate its performance, thereby preventing thieves fromoperating the missing machine and/or component at normal power, whichmay prevent the thieves from moving the missing machine and/or componentto a different location when recovery personnel are en route to themachine's detected location. This also allows the machine and/orcomponent to be recovered more quickly. If the missing machine and/orcomponent is in the middle of operations, service center 20 or portabledevice 50 may transmit a message to the missing machine and/or componentto initiate a delayed derating operation that derates the performance ofthe machine after completing a task, job, etc.
